Description

[0001] This invention relates to the field of silo technology, and in particular to a silo with a cleaning function. Background Technology

[0002] Silos are storage facilities used to store bulk materials. They are divided into agricultural silos and industrial silos, and can store materials such as grain, feed, coke, and cement. Their plan shape is mainly circular, with uniform stress on the walls and high space utilization. Mechanized silos can shorten the material loading and unloading process, reduce operating and maintenance costs, eliminate heavy bagging operations, and facilitate mechanized and automated operations, thus becoming the most important form of storage. During silo unloading operations, after the material flows out by gravity, some material cannot flow out due to natural accumulation; therefore, silo cleaning is necessary.

[0003] During material storage, materials may become damp or accumulate on the inner wall of the silo over time, forming a hardened crust. If this crust is not cleaned promptly, it may mold and deteriorate, affecting the addition and storage of subsequent materials. Existing silos can only remove the remaining material at the bottom to the silo outlet during cleaning, and cannot clean the crust formed on the inner wall. Therefore, there is an urgent need for a silo that can clean the crust formed on the inner wall and has a cleaning function to solve the above problems. Summary of the Invention

[0004] To address the problem that the slabs formed on the inner walls and bottom of the silo during the cleaning process cannot be removed and easily contaminate the materials entering the silo later, this invention provides a silo with a cleaning function.

[0005] The present invention provides a silo with a clearing function, which adopts the following technical solution: A silo with a clearing function includes: The silo body has a feed inlet and a discharge outlet; A floating ring is movably disposed within the silo body, and the floating ring can move along the axial direction of the silo body by means of a first drive mechanism; A silo wall cleaning device includes a cleaning component and a second drive mechanism. The cleaning component is rotatably mounted on the outer periphery of a floating ring and contacts the inner wall of the silo body. The second drive mechanism is configured to drive the cleaning component to rotate along the floating ring to clean the material caked on the silo wall. A cleaning device, rotatably disposed inside a floating ring, is configured to clean the remaining material at the bottom of the silo into the discharge port.

[0006] By adopting the above technical solution, when materials are stored in the silo body, the floating ring is located at the top of the silo body. When the materials inside the silo body are discharged and cleaning is required, the first drive mechanism drives the floating ring to move downward along the axis of the silo body. During the process, the second drive mechanism drives the cleaning component to rotate along the outside of the floating ring. The cleaning component contacts the side wall of the silo body and cleans the hardened material on the side wall of the silo, reducing the probability of the hardened material remaining in the silo for a long time and becoming moldy and deteriorated. It also reduces the corrosion of the silo by the hardened material and extends the service life of the silo.

[0007] Optionally, the first drive mechanism includes at least two lead screws rotatably mounted inside the silo body and a first motor fixedly mounted on the top of the silo body. The axis of the lead screw is parallel to the axis of the silo body. The lead screw passes through a floating ring and is threadedly connected to the floating ring. One end of the lead screw extends into an extension section at the top of the silo body. The output shaft of the first motor is drivenly connected to one of the lead screws. A synchronous pulley is provided between the first motor and the lead screw. At least two of the lead screws are connected by a synchronous belt drive.

[0008] By adopting the above technical solution, the rotation of the first motor can drive multiple lead screws to rotate synchronously. The rotation of the lead screws can drive the floating ring to move up and down, adjust the position of the floating ring in the silo body, and enable a comprehensive cleaning of the inner surface of the silo body.

[0009] Optionally, the cleaning component includes an outer rotating ring and at least one cleaning head movably mounted on the side of the outer rotating ring. The outer rotating ring is rotatably mounted on the outside of the floating ring. The cleaning head has a cleaning end and a connecting end. The connecting end of the cleaning head is provided with a first connecting portion. The outer rotating ring is provided with a matching second connecting portion. The first connecting portion is rotatably connected to the second connecting portion. A groove is provided on the side of the cleaning head near the silo body. A sliding rod is provided in the groove. A slider is slidably mounted on the sliding rod. A third connecting portion is provided on the slider. A fourth connecting portion is also provided on the outside of the outer rotating ring. A support rod is rotatably connected to the third connecting portion. The end of the support rod away from the third connecting portion is rotatably connected to the fourth connecting portion. A spring is provided in the groove near the connecting end of the slider. Under the action of the spring force, the slider tends to move away from the connecting end. When the slider moves away from the connecting end, the cleaning end of the cleaning head moves towards the silo body.

[0010] By adopting the above technical solution, the second drive mechanism drives the outer rotating ring to rotate, and the cleaning head contacts the inner wall of the silo body, which can clean the side wall of the silo body. The spring is always in a compressed state. The spring pushes the slider to move along the slide bar in the slide groove to the side away from the cleaning head connection end. The cleaning end of the cleaning head moves towards the silo body and finally abuts against the inner wall of the silo body. Under the action of the spring, it is always in close contact with the inner wall of the silo body, which improves the cleaning effect of the hardened material on the inner wall of the silo.

[0011] Optionally, the second drive mechanism includes a second motor fixedly mounted on the top of the silo body and a drive rod rotatably mounted inside the silo body and connected to the second motor for transmission. The axial direction of the drive rod is parallel to the axial direction of the silo body. The cross-section of the portion of the drive rod inside the silo body is set as a non-circular polygon. The drive rod passes through the floating ring without contacting the floating ring. A first gear is rotatably mounted on the floating ring. The center of the first gear is provided with a through hole adapted to the drive rod. The first gear and the drive rod are slidably connected. A second gear adapted to the first gear is provided on the inner side of the outer rotating ring. The first gear and the second gear mesh with each other.

[0012] By adopting the above technical solution, the rotation of the second motor drives the drive rod to rotate, the drive rod drives the first gear to rotate on the floating ring, and the rotation of the first gear transmits power to the meshing second gear, which drives the outer rotating ring to rotate along the floating ring, so that the cleaning head can rotate along the inner side of the silo body to remove the caking material inside the silo body.

[0013] Optionally, the clearing device includes an inner rotating ring, which is rotatably mounted on the inner circumference of the floating ring, and a third gear adapted to the first gear is provided on the outer side of the inner rotating ring, wherein the first gear and the third gear mesh with each other.

[0014] By adopting the above technical solution, the rotation of the second motor drives the drive rod to rotate, and the drive rod drives the first gear to rotate on the floating ring. The rotation of the first gear transmits power to the meshing third gear, which drives the inner rotating ring to rotate along the floating ring. When the floating ring reaches the bottom of the silo body, the rotating cleaning device can rotate on the bottom surface of the silo body, conveying the material that has not been cleaned out on the bottom surface to the discharge port, thereby realizing the cleaning treatment of the material in the silo body.

[0015] Optionally, the clearing device further includes two symmetrically arranged spiral conveyor rods, a third drive mechanism connected to the spiral conveyor rods, and a fixed frame fixedly installed in the inner rotating ring. The ends of the two spiral conveyor rods that are far apart from each other are rotatably installed on the inner rotating ring, and the ends of the two spiral conveyor rods that are close to each other are rotatably installed on the fixed frame. The third drive mechanism is configured to drive the two symmetrically arranged spiral conveyor rods to rotate.

[0016] By adopting the above technical solution, the third drive mechanism can drive the two spiral conveyor rods to rotate. The spiral conveyor rods can transport the material to the discharge port in the middle of the bottom of the silo body. During the rotation of the spiral conveyor rods, the inner rotating ring drives the spiral conveyor rods to rotate circumferentially, which can transport the material on the entire bottom surface to the discharge port and discharge it, thus realizing the silo cleaning process.

[0017] Optionally, the third drive mechanism includes a third motor and a transmission assembly connected to the third motor. A fixed plate is fixedly installed between the fixed frame and the inner rotating ring. The third motor is fixedly installed on the fixed plate. The transmission assembly is disposed inside the fixed frame. The transmission assembly includes a first bevel gear and a second bevel gear. Two second bevel gears are provided and fixedly installed at the ends of two spiral conveying rods that are close to each other. The first bevel gear is connected to the third motor and meshes with the two second bevel gears. Both the first bevel gear and the second bevel gear are rotatably connected inside the fixed frame.

[0018] By adopting the above technical solution, the output shaft of the third motor drives the first bevel gear to rotate, the first bevel gear drives the two second bevel gears to rotate in opposite directions, thereby driving the two screw conveyors to rotate in opposite directions. The rotating screw conveyors transport the material on the bottom surface to the discharge port and discharge it, realizing the control of the rotation of two screw conveyors by a single motor.

[0019] Optionally, the silo with the cleaning function further includes a bottom cleaning device. The bottom cleaning device includes a collection shell sleeved on the outside of the spiral conveyor rod and a movable component movably disposed at the front end of one of the collection shells in the rotation direction. One end of the collection shell is fixed to a fixed frame, and the other end of the collection shell is fixedly connected to an inner rotating ring. The end of the movable component away from the collection shell is serrated. The bottom of the collection shell is provided with at least one through-hole. A rotating shaft extends from the front end of the first bevel gear. An eccentric wheel is fixedly connected to the end of the rotating shaft away from the first bevel gear. An eccentric shaft is provided at a non-center position on the eccentric wheel. A fifth connecting part is provided on the movable component. A connecting rod is rotatably mounted on the eccentric shaft. The end of the connecting rod away from the eccentric shaft is rotatably connected to the fifth connecting part.

[0020] By adopting the above technical solution, when the inner rotating ring rotates, the collection shell also rotates synchronously with the inner rotating ring. During the rotation, the material in the silo body will enter the collection shell. The screw conveyor rod will transport the material in the collection shell to the through-hole and finally discharge it in the outlet. The rotation of the first bevel gear drives the eccentric wheel to rotate through the rotating shaft. The eccentric wheel drives the moving parts to reciprocate along the collection shell through the connecting rod. The sawtooth moving parts can clean the material that has hardened at the bottom of the silo body and put it into the collection shell, and finally discharge it in the outlet. When the sawtooth collecting parts encounter more stubborn hardened material, they can crush the hardened material through reciprocating motion, which improves the silo cleaning effect, reduces the probability of the material in the silo hardening and deteriorating, and thus reduces the probability of new material being contaminated after entering the silo.

[0021] Optionally, the collecting shell has a curved section and a horizontal section. The curved section is sleeved on the outside of the spiral conveying rod. A limiting groove is provided at the end of the horizontal section away from the curved section. A limiting plate adapted to the limiting groove is provided on the movable part. The limiting plate is slidably disposed in the limiting groove. A notch is provided on the side of the limiting groove near the eccentric wheel. The fifth connecting part extends out of the notch.

[0022] By adopting the above technical solution, the limiting plate on the moving part can move within the limiting groove of the collecting shell, ensuring the stability of the movement. The material enters the horizontal section and then the curved section. The curved section can temporarily store the material, making it easier for the screw conveyor to transport the material to the discharge port.

[0023] Optionally, a baffle plate is fixedly installed on the top of the fixing frame, and the height of the center of the baffle plate is higher than the height of the surrounding area.

[0024] By adopting the above technical solution, when the material enters through the feed inlet, the baffle plate can help the material and disperse it to the surroundings, which can reduce the probability of the material accumulating in the middle of the silo body after entering, and can also protect the structure inside the fixed frame.

[0025] In summary, the present invention has at least one of the following beneficial technical effects: 1. Through the setting of the silo wall cleaning device, the first drive mechanism drives the floating ring to move downward along the axis of the silo body. During the process, the second drive mechanism drives the cleaning component to rotate along the outside of the floating ring. The cleaning component contacts the side wall of the silo body and cleans the caking material on the side wall of the silo, reducing the probability of the caking material remaining in the silo for a long time and becoming moldy and deteriorated. It also reduces the corrosion of the silo by the caking material and extends the service life of the silo. The second drive mechanism drives the outer rotating ring to rotate, and the cleaning head contacts the inner side wall of the silo body, which can clean the side wall of the silo body. The spring is always in a compressed state. The spring pushes the slider to move along the slide bar in the slide groove to the side away from the cleaning head connection end. The cleaning end of the cleaning head moves towards the silo body and finally abuts against the inner side wall of the silo body. Under the action of the spring, it always keeps in close contact with the inner side wall of the silo body, which improves the cleaning effect of the caking material on the inner side wall of the silo.

[0026] 2. With the cleaning device, the third drive mechanism can drive the two screw conveyors to rotate. The screw conveyors can transport the material to the discharge port in the middle of the bottom of the silo body. During the rotation of the screw conveyors, the inner rotating ring drives the screw conveyors to rotate circumferentially, which can transport the material on the entire bottom surface to the discharge port and discharge it, thus realizing the cleaning process of the silo. The two screw conveyors can improve the cleaning efficiency of the silo.

[0027] 3. With the bottom surface cleaning device, the collection shell rotates synchronously with the inner rotating ring as it rotates. During the rotation, the material inside the silo body enters the collection shell, and the screw conveyor conveys the material to the through-hole, and finally discharges it through the outlet. The rotation of the first bevel gear drives the eccentric wheel to rotate through the rotating shaft. The eccentric wheel drives the moving parts to reciprocate along the collection shell through the connecting rod. The serrated moving parts can clean the material that has hardened at the bottom of the silo body and put it into the collection shell, and finally discharge it through the outlet. When the serrated collecting parts encounter stubborn hardened material, they can crush the hardened material through reciprocating motion, which improves the silo cleaning effect, reduces the probability of material hardening and deterioration in the silo, and thus reduces the probability of new material being contaminated after entering the silo.

[0030] The following combination Figures 1-12 The present invention will be described in further detail below.

[0031] This embodiment discloses a silo with a clearing function, referring to... Figure 1 The silo includes a silo body 100 for holding materials, a silo wall cleaning device 400 for cleaning materials caked on the silo wall, a cleaning device 500 for cleaning materials at the bottom of the silo body 100, a floating ring 200 for adjusting the vertical movement of the silo wall cleaning device 400 and the cleaning device 500, and a bottom cleaning device 600 for cleaning materials caked at the bottom of the silo body 100. The silo body 100 has an inlet 110 and an outlet 120. The floating ring 200 is movably disposed within the silo body 100 and can move along the axial direction of the silo body 100 by means of a first drive mechanism 300. The silo wall cleaning device 400 includes a second drive mechanism 420. When the material inside the silo body 100 is discharged and needs to be cleaned, the first drive mechanism 300 drives the floating ring 200 to move downward along the axis of the silo body 100. During the process, the second drive mechanism 420 drives the cleaning component 410 to rotate along the outside of the floating ring 200. The cleaning component 410 contacts the side wall of the silo body 100 to clean the hardened material on the side wall of the silo, reducing the probability of the hardened material remaining in the silo for a long time and becoming moldy and deteriorated. The bottom cleaning device 600 cleans the hardened material on the bottom surface of the silo body 100. Finally, the cleaning device 500 conveys the material to the discharge port 120 to complete the cleaning of the material inside the silo body 100.

[0032] Reference Figures 1-2The silo body 100 is cylindrical and has a hollow storage space inside. The floating ring 200 can move up and down within the storage space. The floating ring 200 is circular. When there is material in the silo body 100, the floating ring 200 is located at the top of the silo body 100. The floating ring 200 has three threaded holes and two guide holes arranged in a circular array. The silo body 100 is rotatably connected to three lead screws 310 and fixedly connected to two guide rods.

[0033] Reference Figures 1-2 In this embodiment, the first drive mechanism 300 includes at least two lead screws 310 rotatably mounted inside the silo body 100. In this embodiment, three lead screws 310 are provided. The axial direction of the lead screws 310 is parallel to the axial direction of the silo body 100. The lead screws 310 pass through the floating ring 200 and are threadedly connected to the floating ring 200. One end of the lead screw 310 extends into an extension section at the top of the silo body 100. A first motor 320 is fixedly mounted on the top of the silo body 100. The output shaft of the first motor 320 is connected to one of the lead screws 310. A synchronous pulley 330 is provided between the first motor 320 and the lead screw 310. At least two lead screws 310 are connected by a synchronous belt 340.

[0034] Thus, the rotation of the first motor 320 can drive multiple lead screws 310 to rotate synchronously, and the rotation of the lead screws 310 can drive the floating ring 200 to move up and down, adjusting the position of the floating ring 200 inside the silo body 100, and enabling a comprehensive cleaning of the inner surface of the silo body 100.

[0035] Reference Figure 2 , Figures 4-6 , Figures 8-9 , Figure 12In this embodiment, the cylinder wall cleaning device 400 further includes a cleaning component 410, which is rotatably mounted on the outer periphery of the floating ring 200 and contacts the inner wall of the silo body 100. The second drive mechanism 420 is configured to drive the cleaning component 410 to rotate along the floating ring 200 to clean the material caked on the cylinder wall. The cleaning component 410 includes an outer rotating ring 411 and at least one cleaning head 412 movably mounted on the side of the outer rotating ring 411. The outer rotating ring 411 is rotatably mounted on the outer side of the floating ring 200. An annular groove is provided on the outer side of the floating ring 200, and a matching embedded ring is provided on the inner side of the outer rotating ring 411. The embedded ring is disposed in the annular groove of the floating ring 200. Alternatively, a circular groove is provided between the outer rotating ring 411 and the floating ring 200, and a ball is installed in the circular groove, which is the same as the rotation principle of a rotary bearing in the prior art. The cleaning head 412 has a cleaning end and a connecting end. The connecting end of the cleaning head 412 is provided with a first connecting end. The outer rotating ring 411 is provided with a matching second connecting part 414. The first connecting part 413 is rotatably connected to the second connecting part 414. The cleaning head 412 is provided with a groove 415 on the side near the silo body 100. A sliding rod 416 is provided in the groove 415. A slider 417 is slidably mounted on the sliding rod 416. A third connecting part 418 is provided on the slider 417. A fourth connecting part 419 is also provided on the outer side of the outer rotating ring 411. A support rod 4191 is rotatably connected to the third connecting part 418. The end of the support rod 4191 away from the third connecting part 418 is rotatably connected to the fourth connecting part 419. A spring 4192 is provided in the groove 415 near the connecting end of the slider 417. Under the action of the spring force of the spring 4192, the slider 417 has a tendency to move away from the connecting end. When the slider 417 moves away from the connecting end, the cleaning end of the cleaning head 412 moves towards the silo body 100.

[0036] Thus, the second drive mechanism 420 drives the outer rotating ring 411 to rotate, and the cleaning head 412 contacts the inner wall of the silo body 100, which can clean the side wall of the silo body 100. The spring 4192 is always in a compressed state. The spring 4192 pushes the slider 417 to move away from the connecting end of the cleaning head 412 along the slide bar 416 in the slide groove 415. The cleaning end of the cleaning head 412 moves towards the silo body 100 and finally abuts against the inner wall of the silo body 100. Under the action of the spring 4192, it is always in close contact with the inner wall of the silo body 100, which improves the cleaning effect of the hardened material on the inner wall of the silo.

[0037] Reference Figures 4-6In this embodiment, the second drive mechanism 420 includes a second motor 421 fixedly installed on the top of the silo body 100 and a drive rod 422 rotatably installed inside the silo body 100 and connected to the second motor 421 for transmission. The axial direction of the drive rod 422 is parallel to the axial direction of the silo body 100. The cross-section of the portion of the drive rod 422 inside the silo body 100 is set as a non-circular polygon. The drive rod 422 passes through the floating ring 200 without contacting the floating ring 200. A first gear 423 is rotatably installed on the floating ring 200. The center of the first gear 423 is provided with a through hole adapted to the drive rod 422. The first gear 423 and the drive rod 422 are slidably connected. A second gear 4111 adapted to the first gear 423 is provided on the inner side of the outer rotating ring 411. The first gear 423 and the second gear 4111 mesh with each other.

[0038] Thus, the rotation of the second motor 421 drives the drive rod 422 to rotate, and the drive rod 422 drives the first gear 423 to rotate on the floating ring 200. The rotation of the first gear 423 transmits power to the meshing second gear 4111, which drives the outer rotating ring 411 to rotate along the floating ring 200, so that the cleaning head 412 can rotate along the inner side of the silo body 100 to remove the caking material inside the silo body 100.

[0039] Reference Figures 2-3 , Figure 5 , Figure 7 , Figure 10 In this embodiment, the cleaning device 500 is rotatably disposed inside the floating ring 200. The cleaning device 500 is configured to clean the remaining material at the bottom of the silo into the discharge port 120. The cleaning device 500 includes an inner rotating ring 510, two symmetrically arranged spiral conveying rods 530, a third drive mechanism 540 connected to the spiral conveying rods 530, and a fixing frame 550 fixedly installed inside the inner rotating ring 510. The inner rotating ring 510 is rotatably mounted on the inner circumference of the floating ring 200. A protruding ring is provided on the outer side of the inner rotating ring 510, and an annular groove adapted to the protruding ring is provided on the inner side of the floating ring 200. Alternatively, there may be a groove between the inner rotating ring 510 and the floating ring 200. A circular groove is provided, and a ball bearing is installed in the circular groove. A three-gear adapted to the first gear 423 is provided on the outer side of the inner rotating ring 510. The first gear 423 and the third gear 520 mesh with each other. The ends of the two spiral conveying rods 530 that are far apart from each other are rotatably mounted on the inner rotating ring 510, and the ends of the two spiral conveying rods 530 that are close to each other are rotatably mounted on the fixed frame 550. The fixed frame 550 is a C-shaped frame. The fixed frame 550 includes two parallel first plates and a second plate that fixes the two first plates. A third plate is provided at the end of the first plate that is far away from the second plate. The third drive mechanism 540 is configured to drive the two symmetrically arranged spiral conveying rods 530 to rotate.

[0040] In this embodiment, the third drive mechanism 540 includes a third motor 541 and a transmission assembly that is driven by the third motor 541. A fixed plate 542 is fixedly installed between the fixed frame 550 and the inner rotating ring 510. The third motor 541 is fixedly installed on the fixed plate 542, which ensures the stability of the fixed frame 550. The transmission assembly is located inside the fixed frame 550 and includes a first bevel gear 543 and a second bevel gear 544. Two second bevel gears 544 are provided and fixedly installed at the close ends of the two spiral conveying rods 530. The first bevel gear 543 is driven by the third motor 541 and meshes with the two second bevel gears 544. Both the first bevel gear 543 and the second bevel gear 544 are rotatably connected inside the fixed frame 550. Specifically, the two second bevel gears 544 are rotatably installed on two parallel first plates, and the first bevel gear 543 is rotatably installed on the second plate.

[0041] Thus, the rotation of the second motor 421 drives the drive rod 422 to rotate, and the drive rod 422 drives the first gear 423 to rotate on the floating ring 200. The rotation of the first gear 423 transmits power to the meshing third gear 520, which drives the inner rotating ring 510 to rotate along the floating ring 200. When the floating ring 200 reaches the bottom of the silo body 100, the rotating cleaning device 500 can rotate on the bottom surface of the silo body 100, conveying the material that has not been cleaned out on the bottom surface to the discharge port 120, thereby realizing the cleaning process of the material in the silo body 100.

[0042] The third drive mechanism 540 can drive the two screw conveyors 530 to rotate. The screw conveyors 530 can convey the material to the discharge port 120 in the middle of the bottom of the silo body 100. During the rotation of the screw conveyors 530, the inner rotating ring 510 drives the screw conveyors 530 to rotate circumferentially, which can convey the material on the entire bottom surface to the discharge port 120 and discharge it, thus realizing the cleaning process of the silo.

[0043] The output shaft of the third motor 541 drives the first bevel gear 543 to rotate, and the first bevel gear 543 drives the two second bevel gears 544 to rotate in opposite directions, thereby driving the two spiral conveyor rods 530 to rotate in opposite directions. The rotating spiral conveyor rods 530 transport the material on the bottom surface to the discharge port 120 and discharge it, realizing the control of the rotation of two spiral conveyor rods 530 by a single motor.

[0044] Reference Figure 3 , Figures 10-11In this embodiment, the silo with the cleaning function also includes a bottom cleaning device 600. The bottom cleaning device 600 includes a collection shell 610 sleeved on the outside of the spiral conveyor rod 530 and a movable part 620 movably disposed at the front end of the collection shell 610 in the rotation direction. One end of the collection shell 610 is fixed on the fixed frame 550, and the other end of the collection shell 610 is fixedly connected to the inner rotating ring 510. The end of the movable part 620 away from the collection shell 610 is set in a sawtooth shape. The bottom of the collection shell 610 is provided with at least one through hole 611. A rotating shaft 630 extends from the front end of the first bevel gear 543. An eccentric wheel 640 is fixedly connected to the end of the rotating shaft 630 away from the first bevel gear 543. An eccentric shaft 650 is provided at a non-center position on the eccentric wheel 640. A fifth connecting part 660 is provided on the movable part 620. A connecting rod 670 is rotatably mounted on the eccentric shaft 650. The end of the connecting rod 670 away from the eccentric shaft 650 is rotatably connected to the fifth connecting part 660.

[0045] Reference Figure 3 , Figure 11 In this embodiment, the collecting shell 610 has a curved section and a horizontal section. The curved section is sleeved on the outside of the spiral conveying rod 530. One of the collecting shells 610 has a limiting groove at the end of the horizontal section away from the curved section. The other collecting shell 610 does not have a limiting groove and a movable part 620. The movable part 620 is provided with a limiting plate that is adapted to the limiting groove. The limiting plate is slidably disposed in the limiting groove. A notch 680 is provided on the side of the limiting groove near the eccentric wheel 640. The fifth connecting part 660 extends out of the notch 680.

[0046] Thus, when the inner rotating ring 510 rotates, the collecting shell 610 also rotates synchronously with the inner rotating ring 510. During the rotation, the material inside the silo body 100 will enter the collecting shell 610. The screw conveyor 530 will transport the material inside the collecting shell 610 to the through-hole 611, and finally discharge it in the discharge port 120. The rotation of the first bevel gear 543 drives the eccentric wheel 640 to rotate through the rotating shaft 630. The eccentric wheel 640 drives the moving part 620 to reciprocate along the collecting shell 610 through the connecting rod 670. The serrated moving part 620 can clean the material that has hardened at the bottom of the silo body 100. The material enters the collection shell 610 and is finally discharged through the outlet 120. When the serrated collecting part encounters stubborn caking material, it can crush the caking material through reciprocating motion, which improves the silo cleaning effect and reduces the probability of material caking and deterioration in the silo, thereby reducing the probability of new material being contaminated after entering the silo. The limiting plate on the moving part 620 can move within the limiting groove of the collection shell 610 to ensure the stability of the movement. The material enters the horizontal section and then the curved section in the moving part 620. The curved section can temporarily store the material, which is convenient for the screw conveyor 530 to transport the material to the outlet 120.

[0047] Reference Figures 2-3 A baffle plate 551 is fixedly installed on the top of the fixed frame 550, and the height of the center of the baffle plate 551 is higher than the height of the surrounding area.

[0048] Thus, when material enters through the feed inlet 110, the baffle plate 551 can use the material to disperse it in all directions, reducing the probability of material accumulating in the middle of the silo body 100 after entering, and protecting the structure inside the fixing frame 550.

[0049] It should be understood that this solution also includes a controller. The location of the controller is set by the staff according to the actual situation during operation. The controller is used to control the electrical components used in this solution, including but not limited to the first motor 320, the second motor 421, the third motor 541, and the switch button. The controller is an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is also used in conjunction with a motherboard, memory module, storage medium, and power supply.

[0050] The implementation principle of this embodiment is as follows: First, when the silo body 100 is filled with material, the floating ring 200 is located at the top of the silo body 100. When the material in the silo body 100 is discharged and cleaning is required, the first motor 320 is started. The rotation of the first motor 320 can drive multiple lead screws 310 to rotate synchronously. The rotation of the lead screws 310 can drive the floating ring 200 to move downward, adjusting the position of the floating ring 200 in the silo body 100.

[0051] Simultaneously with the start of the first motor 320, the second drive mechanism 420 drives the outer rotating ring 411 to rotate. The cleaning head 412 contacts the inner wall of the silo body 100, enabling it to clean the side wall of the silo body 100. The spring 4192 remains compressed, pushing the slider 417 along the slide rod 416 within the slide groove 415 towards the side away from the connection end of the cleaning head 412. The cleaning end of the cleaning head 412 moves towards the silo body 100, eventually pressing against the inner wall of the silo body 100. Under its action, it remains in close contact with the inner wall of the silo body 100, improving the cleaning effect on the hardened material on the inner wall of the silo. The rotation of the second motor 421 drives the drive rod 422 to rotate, and the drive rod 422 drives the first gear 423 to rotate on the floating ring 200. Specifically, the rotation of the first gear 423 transmits power to the meshing second gear 4111, which drives the outer rotating ring 411 to rotate along the floating ring 200, so that the cleaning head 412 can rotate along the inner side of the silo body 100 to remove the hardened material inside the silo body 100.

[0052] The second motor 421 rotates, driving the drive rod 422 to rotate. The drive rod 422 drives the first gear 423 to rotate on the floating ring 200. The rotation of the first gear 423 transmits power to the meshing third gear 520, driving the inner rotating ring 510 to rotate along the floating ring 200. When the floating ring 200 reaches the bottom of the silo body 100, the rotating cleaning device 500 can rotate on the bottom surface of the silo body 100, conveying the material that has not been cleaned out to the discharge port 120, thereby realizing the cleaning process of the material in the silo body 100.

[0053] Then, the third drive mechanism 540 drives the two spiral conveyor rods 530 to rotate. The spiral conveyor rods 530 can convey the material to the discharge port 120 in the middle of the bottom of the silo body 100. During the rotation of the spiral conveyor rods 530, the inner rotating ring 510 drives the spiral conveyor rods 530 to rotate circumferentially, which can convey the material on the entire bottom surface to the discharge port 120 and discharge it, realizing the cleaning process of the silo. Specifically, the output shaft of the third motor 541 drives the first bevel gear 543 to rotate, and the first bevel gear 543 drives the two second bevel gears 544 to rotate in opposite directions, thereby driving the two spiral conveyor rods 530 to rotate in opposite directions. The rotating spiral conveyor rods 530 convey the material on the bottom surface to the discharge port 120 and discharge it, realizing the rotation of the two spiral conveyor rods 530 controlled by a single motor.

[0054] When the inner rotating ring 510 rotates, the collecting shell 610 also rotates synchronously with the inner rotating ring 510. During the rotation, the material inside the silo body 100 enters the collecting shell 610. The screw conveyor 530 conveys the material inside the collecting shell 610 to the through-hole 611, and finally discharges it in the discharge port 120. The rotation of the first bevel gear 543 drives the eccentric wheel 640 to rotate through the rotating shaft 630. The eccentric wheel 640 drives the movable part 620 to reciprocate along the collecting shell 610 through the connecting rod 670. The sawtooth movable part 620 can move the bottom of the silo body 100. The caking material is cleaned off and enters the collection shell 610, and finally discharged in the discharge port 120. When the serrated collecting part encounters more stubborn caking material, it can crush the caking material through reciprocating motion. The limiting plate on the moving part 620 can move in the limiting groove of the collection shell 610 to ensure the stability of the movement. The material enters the horizontal section of the moving part 620 and then enters the curved section. The curved section can temporarily store the material, which is convenient for the screw conveyor 530 to transport the material to the discharge port 120, thus realizing the material cleaning treatment of the inner wall and bottom surface of the silo body 100.

[0055] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
